Why there is no space between CardViews on Lollipop?

Question

I try to use the CardView and it works well below 5.0, but looks strange on Lollipop.

Answer 1

You have to add app:cardUseCompatPadding="true" to your Cardview. But just adding that may give you an error. To avoid that error, you also have to add xmlns:app="http://schemas.android.com/apk/res-auto" to your CardView.

For example,

    // Other views here

Some would add card_view:cardUseCompatPadding="true" and xmlns:card_view="http://schemas.android.com/apk/res-auto" instead of those mentioned above. Both ways are correct.

Although previous answers will solve the problem, they didn't explain what each attribute does. So to be more helpful to answer seekers,

cardPreventCornerOverlap attribute adds padding to CardView on v20 and before to prevent intersections between the Card content and rounded corners.

cardUseCompatPadding attribute adds padding in API v21+ as well to have the same measurements with previous versions.
